Abstract
The utility model discloses a super pressurization circle of large -scale superhigh pressure hydraulic press, including Y type sealing washer, first retaining ring, second retaining ring, third retaining ring and O type circle, the second retaining ring is connected to first retaining ring one side, and Y type sealing washer is connected to second retaining ring one side to being equipped with the opening with combination department of second retaining ring, connecting the third retaining ring on the opening, Y type sealing washer tip is equipped with round opening, round opening in -connection O type circle. Compared with the prior art, the utility model discloses the working pressure is high, can prevent effectively that the third retaining ring from being extruded.
Description
Technical field
The utility model relates to a kind of Sealing, is specifically related to a kind of ultra-high voltage sealing ring of large-scale ultrahigh pressure oil hydraulic press.
Background technique
Existing conventional high pressure resistant combination Y-shaped ring sealing material combination is generally polyurethane and the duroplasts of shore A95 degree, withstand voltage rank 70MPa, and coordinate requirement higher to seal clearance, y-type seal ring is when bearing ultrahigh pressure, cylinder body can produce expansion, seal clearance can increase, and reduce the anti-plasticating capacity of back-up ring, the back-up ring on y-type seal ring can be extruded.
Model utility content
The purpose of this utility model is that providing a kind of uses the superhigh pressure sealing part that pressure is high, can effectively prevent third gear circle to be extruded.
For achieving the above object, the utility model provides following technological scheme:
A kind of ultra-high voltage sealing ring of large-scale ultrahigh pressure oil hydraulic press, comprise y-type seal ring, the first back-up ring, the second back-up ring, third gear circle and O type circle, first back-up ring side connects the second back-up ring, second back-up ring side connects y-type seal ring, and be provided with opening with the second back-up ring junction, opening connects third gear circle, y-type seal ring end is provided with circular open, connects O type circle in circular open.
As the further improvement of above-mentioned technology, described second back-up ring top is provided with bevelling.
As the further improvement of above-mentioned technology, described y-type seal ring adopts the high hardness polyurethane of shore D57 degree to make, and the first back-up ring, the second back-up ring and third gear circle adopt duroplasts to make, and O type circle adopts nitrile rubber to make.
As the further improvement of above-mentioned technology, described second gear ring cross-section is triangle.
Compared with prior art; the beneficial effects of the utility model are: adopt duroplasts combination back-up ring design and the high hardness polyurethane material of y-type seal ring use shore D57 degree; and the O type circle filling design of y-type seal ring; boost in pressure will be used to 200MPa; larger seal clearance can be allowed simultaneously; adopt the design of combination back-up ring; well protect y-type seal ring and third gear circle can not be extruded damage; coordinate O type circle in y-type seal ring circular open, effectively prevent circular open from tearing phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-first back-up ring, 2-second back-up ring, 3-third gear circle, 4-Y RunddichtringO, 5-O type circle.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
A kind of ultra-high voltage sealing ring of large-scale ultrahigh pressure oil hydraulic press, comprise y-type seal ring 4, first back-up ring 1, second back-up ring 2, third gear circle 3 and O type circle 5, first back-up ring 1 side connects the second back-up ring 2, second back-up ring 2 top is provided with bevelling, the bevelling degree of depth adjusts according to cylinder body expansion amplitude difference, second back-up ring 2 side connects y-type seal ring 4, y-type seal ring 4 cross section is Y type, and be provided with opening with the second back-up ring junction, opening connects third gear circle 3, y-type seal ring 4 end is provided with circular open, O type circle 5 is connected in circular open, y-type seal ring 4 adopts the high hardness polyurethane material of shore D57 degree to make, first back-up ring 1, second back-up ring 2 and third gear circle 3 adopt duroplasts to make, O type circle 5 adopts nitrile rubber to make, second back-up ring 2 cross section is triangle.
During utility model works, because the utility model Y-shaped ring adopts the high hardness polyurethane material of shore D57 degree to make, adopt the O type circle filling design of y-type seal ring, and be equipped with the design of duroplasts combination back-up ring, pressure is used to rise to 200MPa, allow larger seal clearance simultaneously, y-type seal ring 4 is when bearing ultrahigh pressure, cylinder body can produce expansion, seal clearance can increase, y-type seal ring 4 connects the second back-up ring 2 and third gear circle 3, second back-up ring 2 cross section is triangle, then when the second back-up ring 2 diameter dimension becomes large, large internal diameter gap can not be produced in second back-up ring 2, the root of y-type seal ring 4 can not be bitten when the second back-up ring 2 bounces back, second back-up ring 2 and third gear circle 3 can become large along with the expansion of cylinder body, thus well protect y-type seal ring 4 and third gear circle 3 can not be extruded damage, y-type seal ring 4 circular open coordinates O type circle 5, O type circle 5 can prevent stress and concentrate on the phenomenon causing circular open to tear in circular open position, the degree of depth that second back-up ring 2 bevelling is different and different according to cylinder body expansion amplitude, thus effective time extending the second back-up ring 2 and be not extruded, the utility model effectively solves the superhigh pressure sealing difficult problem in the large seal clearance situation of large-scale ultrahigh pressure oil hydraulic press.
The foregoing is only preferred embodiment of the present invention; not thereby embodiments of the present invention and protection domain is limited; to those skilled in the art; the equivalent replacement that all utilizations specification of the present invention and diagramatic content are made and the scheme that apparent change obtains should be recognized, all should be included in protection scope of the present invention.
